Murray Gell-Mann is one of the leading physicists of the world. He was awarded the Nobel Prize in Physics in 1969 for his work on the classification and symmetries of elementary particles, including the approximate SU(3) symmetry of hadrons. His list of publications is impressive; a number of his papers have become landmarks in physics. In 1953, Gell-Mann introduced the strangeness quantum number, conserved by the strong and electromagnetic interactions but not by the weak interaction. In 1954 he and F E Low proposed what was later called the renormalization group. In 1958 he and R P Feynman...

Much instrumentation has been developed for imaging the trajectories of elementary particles produced in high energy collisions. Since 1968, gaseous detectors, beginning with multiwire chambers and drift chambers, have been used for the visualisation of particle trajectories and the imaging of X-rays, neutrons, hard gamma rays, beta rays and ultraviolet photons. This book commemorates the groundbreaking research leading to the evolution of such detectors carried out at CERN by Georges Charpak, Nobel Prizewinner for Physics in 1992. Besides collecting his key papers, the book also includes...

The Landau Institute for Theoretical Physics was created in 1965 by a group of L.D. Landau's pupils. Very soon, it was widely recognized as one of the world's leading centres in theoretical physics. According to "Science Magazine", the Institute in the 1980s had the highest citation index among all the scientific organizations in the former Soviet Union. These selected papers of the Institute reflect the development of the many directions in the exact sciences since the 1960s. The reader can find the original formulations of well-known notions in condensed matter theory, quantum field theory,...

This book provides a comprehensive review of seminal as well as recent results in the theory of condensed phases, including liquid metals, quantum liquids and Wigner crystals, along with selected applications, especially in the physical chemistry of molecules and clusters. A large part of this work is dedicated to the ThomasFermi semiclassical approximation for molecules and condensed phases, and its extension to inhomogeneous electron liquids and liquid metals. Correlation effects in quantum liquids and Wigner crystallization are other areas of focus of this work, with an emphasis towards...

Reflecting the oeuvre of "a man of two cultures: the culture of pure mathematics and the culture of theoretical physics" (in the words of his long time friend and co-author, Kameshwar Wali), this volume is centred around the notion of symmetry and its breaking. Starting with particle physics, the contents proceeds to symmetries of matter, defects, and crystals. The mathematics of group extensions, non-linear group action, critical orbits and phase transitions is developed along the way. The symmetry principles and general mathematical tools provide unity in the treatment of different topics....

This book contains selected papers of Prof Nambu who is one of the most original and outstanding particle theorists of our time. This volume consists of about 40 papers which made fundamental contributions to our understanding of particle physics during the last few decades. The unpublished lecture note on string theory (1969) and the first paper on spontaneous symmetry breaking (1961) are retyped and included. The book also contains a memoir of Prof Nambu on his research career.

Coming into the 21st century, developments in three major areas of elementary particle physics — the electroweak theory with the Higgs mechanism, quantum chromodynamics, and string theory began to yield more and more concrete and successful results.Seeds of all these developments in contemporary particle physics were sowed by Nambu in prophetic lectures and papers from the 1960s-70s.The discovery of the Higgs-like scalar particle at the Large Hadron Collider in July 2011 was the climax for the idea of spontaneous symmetry breaking that Nambu had laid down at the beginning of the...
